母乳喂养会抑制卵巢功能，导致闭经和不孕。母乳喂养的频率和持续时间似乎对维持母乳喂养很重要，而夜间吸吮似乎尤为关键。补充喂养可能会通过改变哺乳行为来影响生育能力，但补充喂养是否会减少闭经的持续时间并增加受孕的风险，这一证据令人困惑。营养较好的母亲闭经的时间往往比营养不良的母亲短，这可能是因为婴儿需要较短的时间来获得所需的营养。然而，它不能被认为是一个可靠的避孕在个人层面上。(C)1997 Elsevier Science爱尔兰有限公司
Breastfeeding suppresses ovarian activity resulting in amenorrhea and infertility. The frequency of breastfeeds and their duration appear to be important in maintaining amenorrhea-and night-time sucking appears to be particularly crucial. Supplementary feeding may affect fertility by altering suckling behaviour, but the evidence is confusing as to whether feeding supplements reduces the duration of amenorrhea and increases the risk of conception. Mothers who are better nourished tend to have a shorter period of amenorrhea than the malnourished, possibly because the infant has to suckle for a shorter period to obtain the nourishment needed, Lactation has an important effect on fertility at the population level. However, it cannot be considered a reliable contraceptive at an individual level. (C) 1997 Elsevier Science Ireland Ltd.
